Combined lightning current and surge arrester, BLITZDUCTOR XTU, 920349

Space-saving combined lightning current and surge arrester module with
actiVsense technology and LifeCheck technology for protecting 2 pairs - with the same or different operating voltages - of balanced interfaces with galvanic isolation. Automatically detects the applied operating voltage of the useful signal and optimally adapts the voltage protection level to it.
Technical data:
- maximum continuous d.c. voltage: 180 V
- maximum continuous a.c. voltage: 127 V
- universal voltage type with actiVsense-technology
- according to the lightning-protection-zone concept applicable to the
  interfaces 0A - 2 and higher
- with integrated LifeCheck monitoring
